The organ in human body where glycogenolysis takes place?

Options

A. Large intestine
B. Liver
C. Small Intestine
D. Kidney

Answer

**Step-by-Step Solution:**

1. **Understanding Glycogenolysis**: Glycogenolysis is the biochemical process where glycogen, a stored form of glucose, is broken down into glucose molecules. This process is crucial for maintaining energy levels in the body.

2. **Identifying the Organs Involved**: Glycogen is primarily stored in two main organs in the human body: the liver and skeletal muscles.

3. **Conditions for Glycogenolysis**: Glycogenolysis occurs under specific conditions:
- When the body requires extra energy, such as during physical activity.
- When blood glucose levels drop, the body initiates glycogenolysis to release glucose into the bloodstream to maintain normal glucose levels.

4. **Evaluating the Options**: The question presents multiple options for the organ where glycogenolysis occurs:
- **Option 1: Large Intestine** - This is incorrect as the large intestine does not store glycogen.
- **Option 2: Liver** - This is correct as the liver is a primary site for glycogenolysis.
- **Option 3: Small Intestine** - This is incorrect as the small intestine is not involved in glycogen storage or breakdown.
- **Option 4: Kidney** - This is also incorrect as the kidneys do not perform glycogenolysis.

5. **Conclusion**: Based on the evaluation, the organ in the human body where glycogenolysis takes place is the **liver**.

**Final Answer**: The organ in the human body where glycogenolysis takes place is the **liver**.
